Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Sign up at stormglass.io and get an API key from the dashboard (free tier: limited requests/day, non-commercial use only).
Call the marine point forecast endpoint (/v2/marine/point per current docs) with lat, lng, and a params list (e.g., waveHeight, swellDirection, currentSpeed).
Pass your API key via the Authorization header.
Optionally specify start/end timestamps for the forecast window and a source parameter to pick a preferred weather model.
Parse the JSON response's per-hour data, noting each parameter may include multiple values from different source models.
Known gotchas
The free tier (roughly 10 requests/day) explicitly disallows commercial use - check current terms before shipping a paid product on it.
Each requested parameter can return multiple source-model values per hour rather than a single number - decide how you'll pick/aggregate a source.
Forecast horizon is limited to about 7 days out; it is not a source for long-range or historical marine data.
